The ADAU1788 is a codec with two inputs and one output that incorporates two digital signal processors (DSPs). The path from the analog input to the DSP core to the analog output is optimized for low latency and is ideal for noise cancelling headsets. With the addition of just a few passive components, the ADAU1788 provides a noise cancelling headphone solution.Note that throughout this data sheet, multifunction pins, such as BCLK_0/MP1, are referred to either by the entire pin name or by a single function of the pin, for example, BCLK_0, when only that function is relevant.ApplicationsNoise cancelling handsets, headsets, and headphonesBluetooth ANC handsets, headsets, and headphonesPersonal navigation devicesDigital still and video camerasMusical instrument effect processorsMultimedia speaker systemsSmartphones
